UNITED STATES PATENT OFFICE.

NICHOLAS U. ORRIGK, OF CANTON, MISSISSIPPI.

PLOW.

SPECIFICATION forming part of Letters Patent No. 228,835, dated June 15, 1880.

Application filed July 25, 1879.

To all whom it may concern:

Be it known that I, N. O. ORRICK, of Canton, in the county of Madison and State of Mississippi, have invented certain new and useful Improvements in Flows; and I do here by declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a perspective-view. Fig. 2 is a longitudinal sectional view; and Fig. 3 is a detail view of the device for securing the plow upon the standard.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to shovel-plows 5 and it consists in certain improvements in the construction of the same, as hereinafter shown and described, and pointed out in the claim.

In the drawings, A represents the beam, and BB the handles. The standard 0 is composed of two pieces, D D, curved in a forward direction, and connected at the lower end by a block, E, to which both are suitably secured.

At the top the pieces D D are hinged to the sides of a lug, F, projecting downwardly from an inclined plate, G, secured upon the under side of the beam. The rear end of plate G is provided with transverse teeth orcorrugations, as represented at H.

Between the pieces D D of the standard, upon a bolt, I, is pivoted a plate, J, consisting of an upwardly and rearwardly extending arm or brace, K, and a downwardly and rearwardly extending arm or guide, L, suitably bent or curved, as represented in the drawings.

The upper end of the arm K is proy'ided with a transversely toothed or corrugated plate, M, engaging the toothed portion of the inclined plate G, and secured by a bolt, N, passing through a A-shaped slot, 0, in the, beam and plate G.

The arm L forms a guide, by which the operation of the plow is steadied, and thus facilitated.

For securing the plow upon the standard, I employ a clamp, P, the lower part of which may be corrugated, so as to engage or grasp a similarly corrugated portion, Q, upon the lower side of the standard.

The sides R R of the clamp are notched to receive the rear or upper end of the plowblade, which latter is secured by a bolt, S, passing through it, and the clamp I as shown. The plow in this manner is firmly and solidly secured, and may be readily exchanged for one of a different kind.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation of my invention will be readily understood.

By loosening the nut upon the bolt N the brace K may he slid to any desired position, thus adjusting the standard and the plow to any desired pitch. The /\-shaped slot 0 enables bolt N to rock sufticiently for this purpose. Bar K braces the standard firmly, and the guide L makes the operation steady and much easier for the operator. The brace K, the plate M of which abuts against the inclined plate G, braces and strengthens the standard very securely.

Having thus described my invention, I claim and desire to secure by Letters Patent ot' the United States- The beam A, toothed plate G, having A- shaped slot 0, hinged standard 0, and plate J, pivoted to the standard and provided with gnideL and brace K, the latter having toothed plate M, engaging the toothed portion of plate G, to which it is adjustably secured by a bolt, N, all combined, arranged, and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

J. W. MAXWELL, M. RUssELL.
